cpu fan is not connected on the screen & beeps

The fact that the old fan didn't give this message makes me think it's likely to be a hardware not a software issue. Have you tried the obvious and checked that the new fan is plugged in firmly and is working. I recently changed the fan on mine and because of difficult access to the power supply socket hadn't pushed the connector all the way, I was rather surprised when a previously healthy PC not only wouldn't boot but started playing peculiar music.
